1. Solo Leveling Was Originally a Web Novel
Before becoming an anime phenomenon, Solo Leveling started as a web novel written by Chugong.
The novel was first published online in South Korea in 2016 on a digital platform for serialized fiction. At that time, no one expected it to become a global hit. However, readers quickly became obsessed with the story’s unique mix of:
RPG-style leveling mechanics
-
dungeon raids
-
intense action
-
an underdog protagonist
The popularity of the web novel eventually led to a webtoon adaptation, which exploded in popularity worldwide.
2. The Webtoon Art Was a Huge Part of Its Success
One of the biggest reasons Solo Leveling became so popular was the incredible art style of the webtoon illustrated by Jang Sung-rak, also known as Dubu.
The illustrations were known for:
cinematic fight scenes
-
detailed monster designs
-
dramatic lighting effects
-
iconic character poses
Many fans consider the Solo Leveling webtoon one of the best-looking action manhwa ever created, which helped attract millions of readers internationally.
Sadly, Jang Sung-rak passed away in 2022, but his work remains one of the most influential contributions to modern webtoon art.
3. Sung Jin-Woo Wasn’t Originally Meant to Be So Dark
At the beginning of the story, Sung Jin-Woo is portrayed as a weak but kind hunter who constantly risks his life just to support his family.
However, as he gains power through the mysterious System, his personality gradually changes. He becomes:
-
colder
-
more confident
-
more intimidating
This transformation was intentional by the author. The idea was to show how absolute power slowly reshapes a person’s mentality.
By the time Jin-Woo becomes the Shadow Monarch, he feels almost like a completely different character from the fragile hunter seen in the first chapters.
4. The “System” Concept Was Inspired by Video Games
The leveling system in Solo Leveling feels incredibly similar to mechanics from MMORPG games.
That’s not a coincidence.
The author was inspired by RPG elements such as:
-
experience points
-
quests
-
skill trees
-
leveling mechanics
-
inventory systems
This design made the story feel familiar to gamers while still maintaining the dramatic tension of a fantasy action series.
Because of this structure, many fans often describe Solo Leveling as “an anime that feels like playing a game.”
5. The Anime Took Years to Become Reality
Despite its massive popularity, the anime adaptation of Solo Leveling took several years to become a reality.
Fans had been requesting an anime for a long time, but adapting the series was complicated because of:
licensing issues
-
international popularity
-
production scale required for the action scenes
Eventually, the project was officially announced with animation by A-1 Pictures, the studio known for titles like Sword Art Online and 86.
The announcement immediately went viral among anime fans.
Anime fans also love imagining epic crossovers between their favorite characters. We recently explored some of the anime crossovers fans are most excited to see.
6. The Story Is Set in a World Where Hunters Are Celebrities
In the universe of Solo Leveling, hunters are treated almost like celebrities.
Powerful hunters receive:
government attention
-
corporate sponsorships
-
media coverage
-
extremely high salaries
Some top-rank hunters are even considered national assets.
This concept reflects a world where power determines social status, making hunter rankings incredibly important.
7. The Shadow Army Is Inspired by Dark Fantasy
One of the coolest elements in Solo Leveling is Jin-Woo’s Shadow Army.
After becoming the Shadow Monarch, Sung Jin-Woo gains the ability to resurrect defeated enemies as shadow soldiers.
Some of the most famous members include:
-
Igris
-
Beru
-
Iron
This dark ability was inspired by classic dark fantasy tropes involving necromancy and undead armies.
However, Solo Leveling turned this concept into something unique by giving each shadow soldier a distinct personality and role.
8. Solo Leveling Helped Globalize Manhwa
Before Solo Leveling exploded in popularity, Japanese manga dominated the global comic industry.
However, the success of Solo Leveling played a major role in increasing worldwide interest in Korean manhwa.
Today, many readers around the world actively search for Korean webtoons, thanks in part to the massive popularity of Solo Leveling.
In many ways, the series helped prove that manhwa could compete globally with manga and Western comics.
9. The Power Scaling Is Extremely High
One thing that makes Solo Leveling so exciting is the dramatic increase in power levels throughout the story.
At the beginning:
-
Jin-Woo struggles against weak dungeon monsters.
Later in the series:
-
he fights powerful monarchs
-
he commands an army of shadows
-
he becomes one of the strongest beings in existence.
This extreme power scaling is one of the reasons fans love the series so much—it constantly raises the stakes.
10. The Ending Is Different From What Many Fans Expected
The ending of Solo Leveling surprised many fans.
Without going into major spoilers, the final arc introduces a time-altering decision that completely changes the outcome of the world.
Some readers loved the ending because it gave the protagonist a chance to protect humanity.
Others felt it erased many sacrifices made throughout the story.
Even today, the ending remains one of the most debated aspects of the entire series.
